Compliance Standards / High-Risk Items for Surface Passenger Ropeways
The components listed below are high-risk items that must be inspected regularly to ensure public safety. During periodic inspections, TSSA inspectors will be checking these items and orders will be issued for non-compliance.
Note: In some circumstances, orders may be issued where high-risk safety hazards are discovered which are not identified in this standard.
SHUT DOWN - If an item is deficient and an order is issued for immediate compliance (0 days for the compliance time):
A repair can be done immediately during the maintenance unless it is a reportable incident according to the Incident Reporting Guidelines. Even if it is a reportable incident, a TSSA Supervisor or Investigator can authorize an immediate repair
REPAIR / REPLACE - If the item is deficient and an order is issued for compliance within a 14-day time period:
